CHARLES OfBALDl/VIN, OF MOMENOE, ILLINOIS, ASSIGNOR OF ONE-HALF TO FRANK S. HUPP, OF SAME PLACE.

OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 519,754, dated May 15,1894.

Application iiled September 4, 1893. Serial No. 484.803. (No model.)

To all whom it may concern:

Be it known that I, CHARLES C. BALDWIN, a citizen of the United States, residing at Momence, in the county of Kankakee and State of Illinois, have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel construction in an oil burner adapted more especially for use in connection withcrude oil, the object bein g to provide a device of this character which can be efiiciently regulated to control the flame and also readily cleaned of the dirt and sediment which may be deposited therein from the oil.

The invention consists in the features of construction and combinations of parts hereinafter fully described and speciiically claimed.

In the accompanying drawings-Figure 1 is a central longitudinal section of an oil burner constructed in accordance with my invention. Fig. 2 is a section taken on the line 2-2 of Fig. 1.

Referring now to said drawings, l indicates the burner or opening at which combustion takes place, and in accordance with my invention said opening communicates with an oil supply opening 2, an air supply 3, and a steam supply 4. The said opening 1 is made through a removable tip 5 that screws into the end of the casting' of the oil burner, so

`that it can be removed and replaced by others when burned out. The casting @comprises a steam chamber 7 with which the steam supply port 4 communicates, and a cylindrical extension or pipe 8 that leads from the steam chamber 7 diametrically opposite the opening l. The said extension or pipe 8 is interiorly screw-threaded at its inner end to receive the screw-threaded portion of a nozzle 9 that is located therein and extends into the steam chamber and also beyond the end of the said extension or pipe 8. Beyond the said extension or pipe 8 said nozzle 9 is provided with a hand-wheel10 by means of which it can be turned to move the end of the nozzle toward or away from the opening 1 to regulate the amount of steam passing into the said opening and thereby controlling the flame. Upon the end ofthe extension or pipe 8 is a packing gland 11, by means of which a tight connection is made between the nozzle 9 and the said extension or pipe, as will be manifest. The passage through the said nozzle 9 is smaller atits inner end than at the outer end, and the said passage or opening of the outer end portion of said nozzle indicated" by 12 is smooth and is adapted to receive one end 13 of what I term, for convenience of description, a coupling 14. The said end 13 of the coupling 14 consists of a tube or pipe that lits nicely within the enlarged portion 12 off the passage of the nozzle and can be slid back and forth therein, while a packing gland 15 on the end of the nozzle 9 serves to maintain a tight joint between these parts.

The oil supply vport 2 is preferably cast in-`` tegral with the casting 7 and communicates with a passage 16 in said casting, which, when the burneris in operation, convenientlystands in a vertical position. The said passage 16 communicates at its lower end with the set?? tling chamber 17, and leading from thesettling chamber is another passage 18 that leads upwardly and communicates with a small passage 19 controlled by a valve 2O in the extension or pipe 2l leading from the oil supply casting. The settling chamber 17 is provided with a removable plug 22, as clearly shown in Fig. 2. The said extension or pipe 21 of the oil supply casting 22 is bored out smoothly to receive the end 23 of said coupling 14, which end 23 consists of a pipe or tube that tits nicely within said bore, and a packing gland 24 serves to maintain a tight connection between said parts. In this way it will be seen that oil entering the port 2 will pass through the passage 16, Settling chamber 17 and passage 18 to the coupling 14 and therethrough into the nozzle 9. It will also be further seen that the quantity of oil can be regulated by the valve 20, and also that any sediment or dirt in the oil that accumulates in the settling chamber 17 can be readily removed from the burner Without disturbing the connections thereof, by simply removing the plug 22 and cleaning the chamber. This is a marked advantage in a device of this kind, for in practice it is found that the IOO dirt present in the oil very often so clogs the burner that it is necessary to discontinue the use of the same,'that it may be cleaned, and by thus providing a settling chamber which collects a'large amount of the dirt, and which can be easily cleaned, I add to the efficiency of an oil burner. The said coupling 14 which leads the oil to the nozzle from the oil supply port is also a further and separate improvement, for it will be noted that it can be easily removed from the burner as the ends of the coupling, which consists of the pipesc13 and 23, have a sliding but oil tight connection with the parts of the oil burner that they enter. The said coupling can therefore be removed Without disturbing the other parts of the apparatusor removing the burner from its normal position, all that is necessary being to cut o the oil and steam supply. In this way the coupling can be removed and cleaned while the other parts of the burner can also be cleaned to remove such sediment, it being also noted that the nozzle 9 can be readily removed. The said coupling 14 comprises the said pipes 13 and 23 and the connecting piece 25 With which each of these pipes communicates. The said connecting piece 25 has a passage 26 communicating at its opposite ends with the said pipes 13 and 23, while a partition 27 in said connecting piece divides the same into two passages, one of which is the passage 26 and the other being a passage 28 communieating with the air port 3. At the end of the connecting piece 25 with which the pipe 13 communicates, the said passages 26'and 28 join each other, as clearly shown in Fig. 1. In this way it will be seen that the supply ot' air is taken in by the oil asit passes through the coupling 14. ,Y Y Y I claim as Ymy invention- 1 .The combinationin an oil burner of a burner opening 1, a steam supply'port communicating therewith, a nozzle for supplying oil to said opening 1, an oil supply port 2 communicating with an extension or pipe 21, and a coupling 14 for conveyingthe oil from said pipe or extension 21 to the said nozzle and having a separable sliding connection with said parts, substantially as described.

2. In an oil burner the combination with the oil supply port and with the nozzle for conveying the oil to the burner opening, of a coupling 14 havinga separable sliding connection at its opposite ends with said oil supply port and with said nozzle and having a partition dividing a portion of the sameinto two passages 26 and 2S, said passagei28 communicating at its opposite ends with theatmosphere and with said passage 26, and said passage 26 communicating at its opposite ends with the passages leading to the oil supply port and to the said nozzle, substantially as described.

3. The combination in an oil burner, of Va burner opening 1, a steam supply port communicating therewith, a nozzle for supplying mixed oil and air to said Aopening 1, an oil supply port 2 communicating with an extension or pipe 21, a coupling 14:for conveying the oil from said extension or pipe 21 to said nozzle and having a separable sliding connection with said parts, and an air supply port communicating with said nozzle, substantially as described.

4.77An oil burner having a steam chamber 7 communicating with arsourceesupplying steam thereto, a burner opening at one side of said steam chamber, a nozzle 9Y having its ends located opposite said burner opening and being longitudinally adjustable, an oil supply port communicating with a pipe orY extension 21 and controlled by a valve 20, and a coupling 14 communicating with said pipe or extension 2l and with said nozzle 9 and having a separable sliding connection with said parts, substantially as described.

In testimony whereotl I affix my signature in presence of two witnesses.
